We build quite a few cables ourselves, and we go through a lot of heat shrink labels. Unfortunately, we only use Brady heat shrink labels, so I don't know if I can help much. Are you actually running raw heat shrink through your printer? If so, go

We use the Brady parts, from the PS-094 up thru the PS-500 size, on a Brady 300MVP printer. We also use that printer for marking Brady polyimide labels. The problem is when we try to print on the smaller markers the printing keeps wandering off the

Hey fellas. Listen, I'm trying to see what the industry as a whole is doing with regard to placement and reflow of the tiny QFN devices. Not the larger ones, but the 4mm or 5mm ones. We struggled a bit with a QFN24, 5mm square. The thermal pad undern

I would concur with the above comments. We have used Juki/Zevatech from the 570L model on and run a full complement of 700 series machines. I have a 10 year old 730 machine that still cranks out product every day over two shifts without problems. Yo

The dumbest thing I read was the response to me saying people should not automatically send product to China. I was told not to bury my head in the sand. A lot of companies are being lemmings and taking it for granted it's best to send a product to C

Good Morning, We also are using Mirtec. We have a total of 5 machines now. 3 in SMT, 1 in RoHS and 1 in Through Hole. We have had incredible luck with these machines and their service is outstanding. I do not have any experiance with the other machi

The use of booties isn't required per se, just considered a standard step necessary to reach the 10,000 target. You also need to vacuum (central vac system, NOT exhausting into the room) daily, mop weekly, have a one piece floor, blah, blah, blah....

Hello, we are facing some troubles with BGA opens in our production. PCB are both side popolated with BGA. BGA is array of 26*26, with some 6*6 center balls. PCB has 2 reflow processes, 4 pcs of BGA on each side. Now we are partly observing opens

Whether there's a fillet or not depends on the component type. Most have a fillet but some, such as QFN's, don't necessarily have one. Have a look at IPC-610D Workmanship Standards to understand when you should expect one and when you shouldn't. T

The reject rate of yours could be a number of reasons. 1. Which component types are rejected? 2. From a particular nozzle? 3. If the rejected part will be dropped on the reject belt or reject bin; it suggests that there is a problem with the componen
